Best to get strut shortened with shorter inserts that are adjustable. Depends if you want to lower it heaps or not as stock struts can bottom out with lowered king springs even.

Also adjustables will work well tuning to the springs. I'm running 250 lb street and I think they are borderline rough for street. You shouldn't need more than 275 but I even think I'd be better with 225lb at times.

I'm running shortened 200b with cool overs and adjustable nos ex us konis. They are 51mm strut not 46mm like you have(hard to find inserts for 46mm!ones )

hi guys, looking at getting some coil overs made up for my ute very soon. I've got 120y struts atm and looking at keeping them aswell. I've just got a few questions that i need answers to before i go ordering parts and sending the stuff away to get welded etc.

1. What spring rate should i look at getting? i want something for street and track use but i do want it fairly stiff for drifting.
2. What strut insert should i look at getting? Looking for something cheap and effective. Are adjustable shocks needed?
3. Do i need to get the strut shortened?

thanks
